The never-ending story

or: yet some more pulleys

Considering I am a countermarche convert since first I tried one, it is interesting how odd counterbalance set-ups seem to come my way...

Have been to a flea-market again. Found some CB pulleys again. This time a pair of homemade(?) two-level type:

They look almost like the standard type, still sold:

- with the exception of all the extra holes.
They must be there for a reason, but which? To change the position of the pulleys? But if so, why?

DH speculated it was to be able to maximize the shed size.
But would that even be true, as, after all, the size/length of the horses (and their cords) must be so much easier to change than having to fiddle with a peg?
(Also considering the height of the reeds "way back when" - my old reeds measure between 5 and 8 cm, so theoretical shed size cannot have been a big question :-)

I left them at the flea market. Should anybody be interested, they will probably still be there for some time... light-weight and easy to pack. (Price? Don't know, unmarked) - come to think of it, there were also a couple of old-fashioned dräll pulleys, more or less like these

though I can't remember if 3, 4 or 5 levels. Again unmarked, but perhaps I could get a good price for both?
(If they are to be sent by post, they will probably not reach anywhere before x-mas)
